Abraxas had at least one child, Lucius Malfoy, who was born in 1954. He apparently knew Horace Slughorn, according to Slughorn and Draco Malfoy.

Abraxas Malfoy was widely belived to have been part of the shady plot that, in 1968, forced Minister for MagicNobby Leach (the first Muggle-born ever to have held the office) to leave his post prematurely. Nothing was, however, conclusively proven against Malfoy.[2]

Abraxas died of a case of dragon pox, a relatively common malady of the elderly, some time before September 1996. Horace Slughorn knew him at one time and was sorry to hear that he had passed away, as he informed Abraxas's grandson Draco.[3] Abraxas may also have been a well-respected wizard, as Draco attempted to use his name to charm Slughorn into letting Draco into the Slug club, because Slughorn was impressed with heritage. However, the name was not good enough to earn Slughorn's favour.

Etymology

The word Abraxas was engraved on stones that were considered amulets in the Ancient Roman-Greco world. They often had figures carved on them as well that resembled basilisks or chimaeras. The name may be related to the word abracadabra, which is notable as this may also be the root of the Killing Curse incantation "Avada Kedavra". The name Abraxas is also mentioned in Gnostic texts, and in Ancient Egyptian mythology as a god or demon.
